The Kinkiness Index

Above is a detail from a breakdown of the sex scenes in the Fifty Shades of Grey trilogy. (Full graphic here.) Rob Orchard explains the project:

An infographic like this is always going to have a slightly subjective and impressionistic element to it—what one person thinks of as the height of sauciness, another will see as unexceptional—but we tried to make it as scientific as possible. We mapped out the sexual acts, locations and paraphernalia for the books, then rated them against scales we had created, running from 1 (Vanilla) to 5 (Kinky). So the sex acts scale ran from foreplay to flogging, sex locations ran from "in the imagination" to the infamous Red Room of Pain, and sex paraphernalia ran from Ben and Jerry’s ice cream to leather shackles and vibrating wands. The Agglomerated Kinkiness Index just pulls together all three ratings to provide an overall kink reading.
